I'm' trying to bring up a test ovirt 4.4 cluster with sr-iov
virtual
infiniband interfaces on Mellanox ConnectX-6 cards in some older Opteron
servers while we await delivery of new Epyc servers.
I have the hypervisors configured for sr-iov and showing the interfaces,
but when I try to bring up a VM with the host device selected it fails to
boot. "Failed Launching ..." shows up on the engine UI.
[image: sriov-hostdev.JPG]
The /var/log/libvirt/qemu log for the VM seems to think something is
wrong with the IOMMU group. If I scroll over to the right it says N/A
under the IOMMU column. Is there some step I need to 'create IOMMU
groups' or any other suggestions?
Any chance to try another PCI slot?
